Was this man, confessed mass-murderer, Anders Behring Breivik driven by coldblooded violence - or mental illness?
That's the question facing Norwegian judges on the last day of Breivik's trial for the killing of 77 people last July.
Prosecutors yesterday argued that, while the 33-year-old's acts were premeditated, there was enough doubt over his sanity to commit him to a mental instutution.
But Breivik, who has always admitted his guilt, has said calling him insane is an insult.
His defence argued on Friday that he had a fundamental human right to take responsibility for his actions.
Defence lawyer Geir Lippestad said Breivik had been driven by an extreme radical belief and attitude, which had to be understood 'within the context of right-wing extremism and culture'.
If Breivik is deemed sane, he faces a 21-year jail sentence which could be extended indefinitely.
A ruling by the two professional and three lay judges is not expected before August 24.
